i will be traveling to yosemite Ntl park between july 25-29th, 2015. i made a reservation for a room for the 25th at a lodge in the park, since i couldn't find an available campground. i am interested in attempting to find a space at camp 4 for the following 3 nights. i was wondering how early i should go there to increase my chance? if somebody experienced in this campground can help me, i will appreciate it.
secondly, i would be interested in hiking through yosemite with a travel companion. i am a 56 year old female academic, originally from turkey, an american for the last 17 years; dedicated to nature, hiking, biking, and camping. looking forward to hearing from the members of this forum.
